Sheltered tidal water such as the Hamble, Dart, Medway, Orwell and the Thames tideway: marina pontoons, swinging moorings, piles and drying mud berths. Marinas and harbours that say they take boats over 20m (65ft): a stated maximum length, or a published price for a boat that size. Canal sites that only take narrowboats are left out; see 70ft narrowboat moorings for those.
